Status Indicator RAPs
11-320-120, 11-322-120 Ejector Movement Failure RAP
11-320-120 The ejector is not at the home position.
11-322-120 The ejector fails to perform a cycle of operation.
NOTE: A cycle of operation for the ejector is to move from the home position to the out position
and back to the home position.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
• Check the 1K LCSS PWB DIP switch settings, refer to 11E-120 1K LCSS PWB DIP
Switch Settings RAP.
• Check for any obstructions that would prevent the ejector from moving.
• If the fault code is 11-322. Check that the screws to secure the motor damper and the
motor bracket are not loose. This will cause the encoder disc to move away from the
encoder sensor. Push the motor bracket towards the encoder sensor and tighten the
screws. Refer to
Figure 1 and REP 11.8-120 .
Procedure
NOTE: All 1K LCSS interlocks must be made to 24V to the motors.
NOTE: In diagnostics, actuating any 1K LCSS sensor or switch can change the displayed state
on the UI. Make sure that the correct sensor or switch is tested.
NOTE: For clarity, the 1K LCSS is shown removed from the machine in Figure 1 .
Refer to Figure 1 . Enter dC330 , code 11-322, ejector out sensor, Q11-322. Actuate Q11-322.
The display changes.

Repair or install new components as necessary:
• Ejector out sensor, Q11-322, PL 11.114 Item 3 .
• 1K LCSS PWB, PL 11.124 Item 1 .
Enter dC330 , code 11-320, ejector home sensor, Q11-320. Actuate Q11-320. The display

• 1K LCSS PWB, PL 11.124 Item 1 .
Enter dC330 , code 11-023 to check the operation of the ejector motor, MOT11-020. MOT11-
020 runs.

Go to
Flag 3 . Check MOT11-020.
Refer to:
• 11F-120 1K LCSS PWB Damage RAP.

Repair or Install new components as necessary:
• Ejector assembly, PL 11.114 Item 1 .
• 1K LCSS PWB, PL 11.124 Item 1 .
Enter dC330 , code 11-023 ejector cycle, check the ejector cycles. Stack the code 11-320 ejec-
tor sensor home, then cycle the ejector. Stack the code 11-322 ejector sensor out, then cycle
the ejector. The ejector actuates the ejector home sensor and the ejector out sensor.

Refer to
GP 7 , check the following components;
• Pulley/drive gear.
• Ejector belt.
Install new components as necessary:
• Pulley/drive gear, PL 11.114 Item 7 .
• Ejector belt, PL 11.114 Item 5 .
The ejector cycles noisily, colliding with the end stops.
Y
N
Check the stapler to ensure the staples are correctly formed, refer to the
11-364-120 Sta-
pling Failure RAP. Mis-formed staples can cause the set to hang in the stapler causing
ejector movement failures. The staples are correctly formed.
Y
N
Clear the staple head of any mis-formed staples, then check the operation of the sta-
pler. If necessary, install a new staple head unit,
PL 11.116 Item 5 .
If the ejector is still not moving, install a new ejector assembly, PL 11.114 Item 1 .
Perform SCP 6 Final Actions.
Go to Flag 4 . +5V is available at P/J8 between pins 7 and 8.
